Wrapping up the Garrett series on a reread, and he's a savage af critic of his earlier works.

They are subtle, but peppered throughout the later books.

For instance, a sorcerer named ShadowSlinger as a play of Shadows Linger.

Then there is recurring madman Barking Dog Amato who's famous for ranting lunacy, and he starts his rant with "There have been Signs and Portents" clearly mocking the start of the first Black Company book (don't care if he's embarrassed, I like it).

There's several more, but I wasn't making notes.

Can not reccomend the series enough if you like the humor of the earlier Company books, the characters are classics.
